I VALVE-REMODELING; DEVICE.

SPECIFICATION forming part of Letters Patent No. 598,662, dated February8, 1898.

Application filed June 10, 1897- 1'0 aZZ whom it may conoerm Be it knownthat 1, CHARLES E. HUXLEY,

of Aurora, in the countyof Kane and Stateof Illinois, have inventedcertain'new and useful Improvements in Valve-Remodeling Devices; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanyin gdrawings,and to the letters of reference marked thereon, which form apart of this specification.

7 This invention relates to an improved device in the nature of ahand-tool for remodeling valve-seats; and it consists in the mattershereinafter described, and pointed out in the appended claims.

In the accompanying drawings,illustrating my invention, Figure 1 is aview in side elevation of a valve, together with an implement embodyingmy invention applied thereto in position for operation. Fig. 2 is asectional view taken on line 2 2 of Fig. 1. Fig. 3 is a detail sectiontaken on line 3 3 of Fig. 2. Fig.- 4 is a detail section taken on line 44 of Fig. 2. Fig. 5 is a sectional view taken on line 5 5 of Fig.4. Fig.6 is a sectional view showing a part of a valve-case with an insertedvalve-seat, such as is adapted to be inserted by my improved implement.of a cutting-tool adapted for use in connec-' tion with the implement."Fig. 8 is an end View of said cutting-tool. Fig. 9 is a sectional viewof the implement when made in a somewhat different form from that beforedescribed.

As shown in said drawings,A indicates a valve-casing, such asthat of anordinary globe-valve, the same being provided with a valve-seat a and ascrew-threaded opening A, in which is inserted. the head which carriesthe valve-spindle.

B indicates a hollow, tapered, and externally-screw-threaded plug whichis adapted for insertion in and engagement with the opening A of thevalve-casing and which serves to support or sustain the other parts ofthe implement in position for action upon the valve-seat. Said hollowplug B is provided in its outer portion with a cylindric screw-threadedrecess B, within which fits a removable ring 0, having external screw-Fig.7 is a side elevation Serial No. 640,136. (No model.)

threads fitting those of the said recess and serving as a means ofretaining the holdingring in place within the said plug. said ring C ismounted a circular plate or disk D, the, same being mounted in the ringin such manner that it may be rotated therein or clamped rigidly therewhen'desired. As herein shown, the ring 0 is provided with an internalcylindric surface fitting the cylindric peripheral surface of theplateand has adjacent to its inner face an inwardly-projecting rib c,engaging the adjacent face of the diskD, and a separate confining-ring Cis secured by screws 0 against the outer face of the'said ring 0, theconfining-ring being adapted to project over the margin of the disk andthe parts being so proportioned that when the screws 0 are tightened thering will be clamped against the disk and hold the same rigidly frommovement. In the said disk D is formed a transverse slot D, Figs.4 and5, in which slot Within is located a sliding block E, which block ismade of a width to fit closely between the side walls of the slot, butof a length considerably shorter than the slot, so that the block may.have endwise movement in the slot. As a means of confining the saidblock within the slot, the block is shown as made thicker than the diskD and as provided at one side with flanges e e and at its opposite sidewith a removable plate E, which is wider than'the body of the block andprojects at the side of the same to overlapthe adjacent surface of thedisk. Said plate E is secured by screws 6 c to the block E, and theparts are so proportioned thatthe said plate may be tightened againstthe disk for the purpose of holding the block from movement'in the slotwhen adj usted to the desired position therein. Mounted centrallywithin'the block E is a swivelplate F, having curved end faces f f,which engage the correspondingly-curved surfaces of a socket in theblockE, said curved surfaces being struck froma commoncenter, so thatthe swivel-plate F is adapted to swing in the block E in a planeparallel with the sides of the block. The swivel-plate is prefsegmentsor spherical segments, the latter construction being that employed inthe form of the implement shown in the accompanying drawings.

G indicates a shaft or spindle which passes centrally through theswivel-plate F and is provided at one end with a hand-crank G,by whichit may be turned or actuated, and has at its opposite end ascrew-threaded portion 9 for the attachment of a cutting-tool, such asthe cutting-head H (shown in Figs. 7 and 8) or the short tap I. (Shownin Figs. 2 and 9.) The swivel-plate F, together with the sliding block'E, disk D, and ring 0, constitute a means for adj ustably supportingthe spindle G in proper position with respect to the valveseat to beoperated upon, and in order to enable the swivel-plate to be rigidlysecured from movement or turning in the block E a clamping device forsaid swivel-plate is provided, which is shown in the accompanyingdrawings as made as follows:

The slot or opening of the plate E is ex tended at one side of theswivel-plate, and in said slot is inserted a bearing-piece F having aconcave surface fitting that of the swivelplate and adapted to bearagainst the same, and a wedge F which is inserted between the saidbearing-piece and the end wall of the slot. Said wedge serves as a meansof tightening the bearing-piece against the swivel-plate, the wedgebeing driven in tightly between the parts, so as to hold theswivel-plate from movement when the spindle has been adj usted to thedesired inclination with respect to the valve-seat to be operated upon.In connection with the device for adjustably supporting the actuatingspindle above described I have herein shown a feed device by which thetool attached to the spindle may be fed or advanced to the work as thesame progresses, one form of such feed device being shown in Figs. 1 and2 and another form in Fig. 9.

Referring first to the form shown in Figs. 1 and 2, J indicates ascrew-threaded sleeve which is secured in the swivel-plate F andsurrounds the part of the spindle adjacent and exterior to saidswivel-plate. Said screwthreaded sleeve J engages the lower end of ayoke K, which engages the spindle at a point above the sleeve and isadapted to turn freely on said spindle, said yoke havingalowerportion orcollar is, which engages the screwthreaded sleeve, and an upper portionor collar which engages the spindle and connecting parts, extendingbetween collars and rig idly connecting the same. Mounted upon thespindle below and in contact with the upper collar 70 of the yoke K isan adjustable collar L, herein shown as consisting of a split ringprovided with a clamping-screw Z, by means of which the ring may betightened on the spindle and thereby held from movement thereon. Saidcollar L serves as a shoulder or abutment against which the upper partof the yoke K acts when the yoke is screwed downwardly upon the sleeve Jin such manner as to force or draw downward the spindle G and therebyforce or carrythe cutting-tool against the valve-seat which is beingoperated upon.

Referring now to the form of feeding device shown in Fig. 9,"J indicatesa sleeve which is attached to the swivel-plate F in the same manner asbefore described in connection with the sleeve J. Said sleeve J,however, is enlarged and made of tubular-form at its upper end and isadapted to receive the lower end of a screw-threaded sleeve M, which ismounted to turn on the spindle above the sleeve J. Said sleeve M isattached to a disk M, which is -provided in its top orouter surface witha concentric recess m, in which fits an outwardlyprojecting flange n,formed upon a sleeve N, which also surrounds the spindle, the flange nbeing confined within the recess by means of a cap-plate m secured tothe margin of the disk M in the manner illustrated. Said sleeve N, whichprojects upwardly from the disk M, is externally tapered andscrew-threaded and is also split longitudinally and provided with a nutN, which when screwed down over the tapered, split, and screw-threadedupper portion of the sleeve serves to clamp the same upon or against thespindle. The connection, described between the disk M and the sleeve Nobviously constitutes a swivel-joint which permits the said disk and thesleeve M to be turned freely on the spindle when the sleeve N is securedthereto, and said sleeve M having screwthreaded engagement with thesleeve J it follows that by turning the disk M the spindle will beforced or carried downwardly through the sleeve J and the swivelplateand thus fed forward to the work. Obviously the sleeve N may be shiftedbackward or forward on the spindle when necessary by loosening the nut Nand again tightening the same when the sleeve has been moved to adesired point on the spindle. A stop-nut N is applied to the spindle Mand may be adjusted to any desired position thereon, so as to come incontact with the upper end of the sleeve J, and thereby limit the inwardmovement of said sleeve in feeding forward the tool to its work.

The flange n is provided with a hole 02', which may be brought oppositea hole m in the disk M, when the end of a rod or other suitableimplement may be inserted into said hole a to hold the sleeve N fromturning in the act of tightening or loosening the nut N on the saidsleeve. As a further improvement in devices of this character the plug Bis provided not only with a tapered externallyscrew-threaded surface Bbut also with an internal tapered screw-threaded surface B adapted tofit over and engage an externallyscrew-threaded tubular projection orneck on a valve-casing, thereby adapting the plug for IIO attachment tovalve-casings having both in ternally and externally screw-threadedopenthread by means of the tap I, as seen in Fig. 2,

and a screw-threaded bushing A Fig. 6, then inserted to form a newvalve-seat. vice for adjusting the inclination of the spindle withrespect to the supporting device andthe valve-seat is intended moreparticularly for use in remodeling valves of that class in which theseats are arranged at an angle wi th respect to the opening in thevalve-casingsuch, for instance, as the gate-valves, in which the movingpart of the valve is of tapered form and enters between twooppositely-inclined valve-seats in a familiar manner. The

devices for adjusting the angle of the spindle block E is then shiftedor moved in said slot to a greater or less distance from the center ofthe disk in accordance with the inclination required to be given to theyspindle in order to bring the cutting-tool accurately in position forits work, it being of course understood that the cutting-tool willpreferably be adjusted to operate concentrically with the valve-seat asoriginally made or formed.

I claim as my invention 1. An implement for remodeling valves comprisinga hollow, tapered plug, a tool-supporting spindle passing through theplug, a bearing for the spindle and means for adjustably supporting thebearing in the plug.
